FEED-WATER CLEANER AND HEATER.

To all whom it may concern:

Be it known that I, EMIL E'FRAN, a subject of the Emperor of Austria-Hungary, residing at Briinn, Austria-I-Iungary, have invented a new and useful Improvement'in Feed-Water Cleaners and Heaters, of which the following is a specification.

My invention relates to steam boilers and especially to cleaning and heating feed water supply for boilers and has for an object, to provide means for separating mud and other impurities from water preparatory to introducing the water into actual contact with the boiler.

Another object of the invention is to heat the feed water to such a temperature that the boiler will not be detrimentally affected, as often results from introducing cold water.

I attain the foregoing objects by the mechanism illustrated in the accompanying drawings in which similar reference characters designate similar parts throughout the several views and in which Figure 1 is a vertical, longitudinal, sectional view of a device embodying my invention; Fig. 2 is a transverse section through one of the troughs or aqueducts; Fig. 3 is a vertical, longitudinal section through a device embodying a modified form of the device comprising my invention; Fig. 4C is a front elevation of the element 2', of Fig. 3; and Fig. 5 illustrates a vertical transverse section, and a vertical, longitudinal section of another modified form of the device.

The device as illustrated in Fig. 1 is designed to be secured in the steam space of a boiler by any suitable means; its location being such that the member 43 shall always be above maximum high water level. In this figure, L is the supply pipe through which water or other liquid is introduced; 17, 18, 19, 20 and 21 are chambers for collecting and retaining impurities from the water, and 40, 4:1, 12 and 13 are aqueducts over which the water passes from one group of chambers to the other group of chambers, and in which heating and evaporation are efiected.

In operation, water from the plpe L enters the chamber 17 under pressure, and rises to the point indicated by the head of arrow 3; thence, entering the aqueduct 4L0,

| gravitates slowly into the chamber 18. It then rises in chamber 18, through 18" into the aqueduct 41 and gravitates into chamber 19, and continues thus to flow and rise, following the direction of arrows 7, 8, 9, 10, 11, 12, 13, 14 and 15; finally making exit through the discharge pipe L into contact with the boiler. Partitions 30,31,32,33 and 34C divide the chamber 17 18, 19, 20 and 21 respectively, and extend approximately near the bottoms of said chambers to insure that the flow of liquid will not be short circuited near the surface. In making the circuit above described, the water in the aqueducts exposes a large area of surface to cont-act with the heat and steam in the boiler, and a large area of surface contacts with the aqueducts, which are heated by the steam surrounding them; therefore, the water that flows from the pipe L is nearly or quite atthe temperature of steam, or at the boiling point. It is well known that heating water causes certain solutions therein to coagulate and settle by gravity, and it will be readily understood that if the flow of water be gradual through these aqueducts and chambers, the latter will retain a major part of the sediment, which is detrimental to boilers and that tends to minimize the efficiency thereof.

VVhile I have described my invention as applied to a steam boiler, it may be also applicable in distilleries or other apparatus wherein evaporation, purification or heating of fluid is desirable. My invention is, therefore, not limited to the foregoing disclosure.

I claim 1. I11 a liquid heating and cleaning device, a group of chambers, each chamber having a partition therein extending from the top into proximity with the bottom thereof, a second group of chambers of similar construction to first said group, a supply pipe and a discharge pipe communicating with said chambers, and inclined aqueducts connecting the two groups of chambers for the purpose specified.

2. In a liquid heating and cleaning device, a number of groups of chambers, aqueduct-s connecting the groups of chambers, each chamber having a partition therein, each said partition depending from the aqueducts and being spaced apart from the botone group With a partition of another group tom of the chamber, supply and discharge of said chambers. 10 means being connected with said chambers. In testimony whereof I have hereunto set 3. In a liquid heating and cleaning demy hand in presence of two Witnesses.
